// Changes: 
//
// Should these be tracked as transactions ? 
// SAT -> SAT
// tracking various exchange variations (outside of external networks ?)
//
// Is user / account / amount info redundant ?
// + transaction_type: deposit / withdrawal / transfer / exchange ?
//
// add transfers table ? (for internal transfers only ?)
// add redemptions table ? (for bitcoin transfers only ?)
// add exchanges table ? (for conversion from one currency to another)
//
// network -> scope:  internal / bitcoin / liquid / lightning ?
// add bitcoin_transaction ?  (with redemption attributes)
// add liquid_transaction ?   ()
// add lightning_transaction ? (with LN_invoice_hash)
// add internal_transaction ? ()
//
// context for path, memo, rate, preimage, address, received, fee, tip, confirmed, redeemcode ?
